Understanding the different biogeochemical conditions that induce precipitation of carbonates and minerals in microbial mats is the key for a better reconstruction of the mechanisms of the formation of fossil stromatolites found in the geological records. I am interested in the investigation of the different microbial populations and metabolisms conducive to the formation of stromatolites, in particular, the examination of anaerobic microbial consortium which promotes the precipitation of different minerals and carbonate build-ups.

Through organic geochemical and micropaleontological analysis, I study the information preserved in sedimentary archives. As part of the Bosak lab, I continue to characterize body fossils from the Neoproterozoic interglacial period to better understand early eukaryotic radiation and possible connections with the dramatic environmental change associated with the Sturtian low-latitude glaciation.

 I am interested in early life on Earth and the evolution of microorganisms and their environments. My current research centers around Cryogenian microfossils found in post-Sturtian cap carbonates. Through microscopic and chemical analyses, I hope to gain insight into what these fossils represent and what they can tell us about ecology in the Cryogenian non-glacial interlude. I am also interested in early evolution of cyanobacteria on Earth and the reconstruction of phylogenetic trees and molecular clocks for this complex group of bacteria.

My current research focuses on microbe-mineral interactions. I employ a variety of microscopy techniques and chemical analyses to investigate the formation of minerals around microbial filaments. My goals are to explore the mechanisms of fossilization and to determine what depositional environments are most conducive to fossilization.

Currently I am investigating how bacterial gas production and consumption vary dependent on atmospheric composition, mainly focusing on photosynthesis. The goal is to have a better estimate about how life could affect the atmosphere on an exoplanet and thereby provide better markers for detecting life in the universe.

My research interests span a range of topics including the geochemical processes that govern the Earth system as well as the origin and evolution of life. I am currently focusing on probing the formation condition of methane by analyzing methane “clumped isotope” (13CH3D) composition. In particular, I am interested in understanding how the effects of biological and non-biological processes manifest in the geochemical signatures.

I am passionate about microbiology. I’m currently interested in understanding how sulfate-reducing bacteria respond to variable environmental conditions, such as nutrient limitation, and how those changes affect their metabolism. Ultimately, this might give us an insight into how sediments are influenced by the microbes living in them.
